Where Blockchain Is Stored: An Explanation of the Basics

Where Blockchain Is Stored: An Explanation of the Basics

Whoever is unfamiliar with blockchain has one simple question: “Where is blockchain stored?” Many users of blockchain through dApps or digital currencies are still unclear about how data is stored and accessible on the blockchain.

With time, blockchain is gaining greater momentum as it rapidly evolves. Currently, there is a multitude of digital currencies available for purchase, storage, and use in the real world. For instance, Hyperledger is one of the open-source projects attempting to tackle business problems by delivering enterprise-ready tools, libraries, and frameworks.

How Does Blockchain Works?

Consider blockchain to be a distributed ledger system in which peers communicate and collaborate to access and store information.

To have a better understanding, let’s consider Jim and Carry. Jim wants to send Carry some money. To do so, he will use his private key and Carry’s public address to initiate the transaction. Then, the transaction is assigned to the block. The block is subsequently confirmed with the aid of the network’s consensus method. The network validates the transactions that use it. 

Once the transaction is fully validated, it is added to the blockchain and the funds are transferred to Carry. Once written, this information is immutable and hence cannot be altered.

The identical procedure can be carried out between two entities. It might be a bank, a business, or a buyer seeking to conduct transactions on the blockchain network.

Where Blockchain is Stored?

Therefore, now that we have a proper grasp of blockchain, we are prepared to discover where blockchain data is stored. The inquiry might also be phrased as “where are blockchain data stored?” Both queries have the same response.

Let’s get started.

The following data is broadcast when a transaction is made in a blockchain.

  • Date and time of the trade
  • The amount transferred from sender to recipient.
  • Sender’s address
  • The recipient’s address
  • The transaction may include other essential information required to ensure its success.

Let’s attempt to comprehend it via the lens of bitcoin. The following data is saved and communicated during a Bitcoin transaction:

  • Transaction date
  • Quantity sent
  • The recipient’s Bitcoin address
  • Address in Bitcoin of the recipient

The transactions are compiled in a bitcoin block’s header. These headers are back-linked to the main blockchain, so producing a blockchain, hence the name “blockchain.”

So, Where Does Blockchain Stored?

There is no straightforward answer.

Since Blockchain is decentralized, there is no central repository for it. This is why it is saved on computers and systems distributed throughout the network. These computer systems are known as nodes. Each node contains a single copy of the blockchain or the network’s transactions.

Consequently, you may compare the blockchain system to a spreadsheet where each entry stores the value of an address. In addition, the spreadsheet is updated anytime there is a change.

Also, do you recall the Jim and Carry example transaction? If you do, then the data is generated, confirmed, and stored in the blockchain as part of the transaction. Here, both Jim and Carry are referred to as nodes. Jim sends the digital cash via his digital wallet.

Additionally, the digital wallet may connect to the network and has a list of other nodes and users. Therefore, once Jim transmits the transaction, it is visible to the entire network.

It is announced to the entire network that Jim has sent Carry a certain sum of money. The broadcast is performed until each node is aware of the transaction. A transaction becomes immutable and irreversible once it has been validated by a small number of nodes known as miners.

Depending on network congestion, the entire procedure could take anywhere from a few minutes to several hours.

Why Would You Want To Store Data On Blockchain?

Now that we know where the blockchain is stored, we must determine whether or not data may be saved in the blockchain. The query is best directed at developers who may wish to store data using blockchain. Ultimately, blockchain has numerous benefits, including enhanced security, immutability, and transparency.

However, blockchain technology is great for storing vast quantities of data. Yes, it cannot be a database if you wish to create a Twitch-like video streaming platform for YouTube.

However, it is perfect for storing a high number of transactions involving modest amounts of data. Blockchain networks are very scalable, and there are numerous blockchain variants that are also highly accessible.


This brought us to the conclusion of our article, in which we covered how data is saved on blockchains and how they are maintained. There is no question that users of various blockchain platforms or solutions can implement a variety of different strategies to accomplish their goals.
